UNITED STATES PATENT @FFIQE Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed December 28,1904. Serial No. 238,584.

To all whom it may concern:

Be it known that I, ISRAEL IV. KELLY, a citizen of the United States,residing at Pawtucket, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inTobacco-Pipes, of which the following is a specification.

This invention appertains to a novel construction of pipe for smokersand embodying the usual bowl-and-stem type of this kind of article.

The essential object of the invention is to provide a means whereby thetobacco, which is being consumed in the bowl, may be kept adjacent theupper or open end thereof, so as to insure perfect combustion and aclean cool smoke.

By keeping the burning tobacco at or perhaps slightly above the openportion of the pipe-bowl the air is permitted to pass thoroughl ythrough the burning tobacco, the bowl is not greatly heated, and thesmoke drawn through the pipe-stem is cool and sweet.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

lVhile the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodimentthereof is shown in the accompanying drawings, in which- Figure 1 is aperspective view of a pipe embodying the essential features of theinvention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is atop plan view of the cap or guard member.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

In the special construction of the invention, as shown in the drawings,the numeral 1 designates the bowl of a pipe and the numeral 2 the stem.The stem 2 is of the usual peculiar form, being of somewhat crook shapepreferably. The tobacco in the bowl 1 is supported by a base or bottom 3of tubular construction in order that it may be adjusted to feed thetobacco toward the open end of the bowl 1 as the same isconsumed in thesmoking of the pipe. The position of the base or bottom 3 of the bowl 1is adjusted by relative movement of the bowl with relation to the stem2, projecting therefrom. In other words, the stem 2 is attached to thebowl 3 in such a man.- ner that by manipulating the bowl with relationthereto the bottom or base 3 may be readily forced upwardly in the bowl1 to raise the tobacco and dispose that portion of the material which isbeing burned or consumed at the upper or open extremity of the bowl 1and so exposed as to facilitate combustion and permit the smoke, whichpasses through the stem 2, to be cooled before it reaches the mouth ofthe smoker. The base or bottom 3 of the bowl 1 is preferably of hollowformation, and the upper side of the base consists of a plate 3, havinga plurality of small perforations through which the smoke is drawn fromthe bowl into the stem 2. The stem 2 is affixed to the member 3 in anysubstantial manner, and adjustment of the bottom or base 3 is admittedof by the provision of threads upon the peripheral portion of the baseand internally threading the bore of the bowl 1, as shown most clearlyin Fig. 2 of the drawings. The threaded connection of the bowl 1 and thebase 3 is shown at 4. The bore or opening in the bowl 1 preferablyextends entirely therethrough, is open at opposite ends from its lowerto itsupper extremity, and by rotating the bowl, the stem being at thesame time held stationary, it will be seen that the base 3may be screwedupwardly in the bore of the bowl to elevate the tobacco therein as thesame is gradually consumed in the smoking operation.

The construction of the bowl 1 and the base is advantageous in that asthe smoker holds the mouthpiece of the stem 2 in his mouth the bowl 1may be readily grasped by the hand and slightly rotated to therebyelevate the bottom 3 in the manner above described. At the upper openextremity of the bowl 1 is located a guard or cap member 5, preferablymade of a plurality of cross-wires, and this member 5 is detachablysecured to the bowl 1 in any suitable manner. The cap member 5 isdesigned to hold the consuming material at the upper portion of thebowland keep the tobacco therein compact. The crook or curved portion ofthe stem 2 is provided with a screwplug 7 leading to the hollow ortubular portion thereof, and by removing this plug any accumulations inthe stem may be readily extracted or removed.

The pipe, as hereinbefore set forth, is very simply constructed and theparts are so ar' ranged as to admit of convenient manipulation thereofby the smoker using the article. The removability of the base or bottommember 3 admits of ready cleaning of the bore or receptacle portion ofthe bowl 1, and the part 3 is of course adaptedto be readily adjusted toa lowermost position relative to the bowl 1 in refilling the bowlpreparatory to smoking. Acommon defect in the pipes at present in use isdue to the fact thatthe bowl of the pipe is ordinarily made very hot bythe tobacco as it is consumed, and the smoke is thereby heated andcaused to have a bad flavor often distasteful to the smoker. of courseobviated in the use of a pipe constructed in accordance with thisinvention and z the smoke is purified and sweet, so as to be conduciveto the comfort of the smoker in a manner which is apparent. The opening;or bore of the bowl 1 is preferably provided with a metal lining ofcylindrical form somewhat, suitably attached to the bowl and earryingthe internal threads, by which the bottom is adjustably mounted thereon.The

lining prevents burning of the bowl if the The above defect is 3 same bemade of combustible material and is otherwise advantageous.

As above mentioned, the bore of the bowl 1 is open at opposite ends. Theabove is advantageous in that the bowl may be quickly removed from thestem and bottom member so as to facilitate cleaning thereof. The threadsof the bowl and bottom member 3 are therefore not likely to becomeclogged, so as to prevent proper operation of the parts.

Having thus described the invention, what is claimed as new is A pipecomprising a bowl having a bore or opening extended theret-hrough andopen at Y its opposite ends. an internally-thriaaded metallic lining forthe bore of the bowl, a perforated base or bottom adapted to be screwedinto the bore of the bowl and having threads l to match the threads ofthe lining thereof, and atubular stem applied to the bottom member ofthe bowl substantially as set forth.

In testimony whereof I afiix my signature in i presence of twowitnesses.
